Now that it is so warm out, I've been motivated to hang clothes on the line to dry. We don't have that great of a system but the savings of money and energy make it worth it to me. (I've read estimates that the dryer can cost around $.50 an hour to run.)
The other great perk to line-drying is that the sun is a natural bleaching agent to whiten up your cloth diapers and wipes!
It's also a lovely reason for me to get outside with the kids and somehow my busyness keeps them occupied on a task too. Today they were spiders creating a huge web (mess of rope)! And hopefully, we will all nap better too!
